Great app!
Easy to use. I've setup the cart recovery in a quick timeline. Overall it's good. I recommend this to everyone!

We were considering omnisend to handle our emails but after downloading we discovered undemocratic and unethical business practices clear which we find unacceptable.
Firstly, they charge by user but do not allow you to upload a supression list which all other email providers allow. It's pretty standard in the industry.
Secondly, if you manually unsubscribe a set of users you don't wish to market to via omnisend, they will aggressively block you from marketing them via any other app by switching the accept marketing status to OFF on shopify. Imagine you have low open rates among a particular set of customers but they respond well to another channel, omnisend will not allow you to remove them unless you remove them fromm all other comms channels... except their own sms and push channels!!
I assume this is because they want total control on push and sms and are unwilling to sit along side other apps. But it's not ethical to force it on merchants.
Just to be super clear, on their site it says: "In Omnisend, the same contact may have different subscription statuses for each of the channels, Subscribed to Emails, and Unsubscribed from SMS or Push Notifications. For that reason, we don't keep a Suppression list"
But over email they will tell you "Contact unsubscribing from marketing = they're unsubscribing from Omnisend = they're unsubscribing from Shopify marketing as well."
I have now deleted the app.

The app is OK quite difficult to use in the beginning if you don't no what your doing eventually get the hang of it but what I found incredibly disappointing was the service!!! I accidentally signed up to sms and wasn't aware it was a monthly thing I don't even use sms I literally needed it for one sms!!! I only use this service for emailing customers Long story short I was charged nearly $60 for one month just for the usual bill and sms when I contacted almost instantly explaining I'd made a mistake and wasn't even aware that it was a subscription I was basically told too bad we don't do refunds and they were more than happy for me to cancel my account and that was the answer for me so I'm currently looking for another company to work with because considering it's a first time mistake it's pretty disappointing. So make sure you don't make any mistakes with payments because you won't see that money again!
